"By logic" is a phrase used to indicate that a certain proposition or conclusion is arrived at through rational reasoning and the application of logical principles. It implies an adherence to the rules of logical inference and deduction, ensuring that the derived solution or decision is valid and sound.
In this context, "logic" refers to the study of valid reasoning, often associated with formal systems and deductive reasoning. It encompasses a set of rules and principles that guide the process of drawing conclusions and making rational judgments based on the given premises or available information.
When someone seeks to solve a problem or make a decision "by logic," it means that they are relying on logical reasoning to reach the best possible outcome. This typically involves identifying relevant evidence or information, organizing it clearly, and applying logical operations such as deduction, induction, or abduction to draw valid inferences and conclusions.
Using logic can help minimize the influence of biases, emotions, and arbitrary assumptions, as it depends on objective analysis and the evaluation of evidence. By following a logical framework, one aims to ensure that their arguments or conclusions are based on sound and consistent reasoning.
Overall, the phrase "by logic" signifies an approach that prioritizes rational thinking, informed judgment, and the use of logical principles to arrive at reliable and widely acceptable conclusions or solutions.
